An asplenic young man needs expert advice when planning an overseas trip

Harry, a 28-year-old new patient, is seeking advice as he is taking a year's leave to travel in six months' time.

Travel health

Harry has no illnesses, and takes no regular medication. He is a nonsmoker and binge drinks alcohol on weekends. He has no allergies.

His paternal family history includes ischaemic heart disease in their 50s. He is fit, exercises and eats healthily. He was fully vaccinated in childhood.

The GP inquires about other vaccines. Harry says he had "heaps" following a car accident at 19, when his spleen was removed and he was "jabbed" repeatedly.
